Product Description
The HP 698531-B21 Smart Array RAID controller is engineered to deliver robust storage performance and data protection for demanding server applications. With its 6Gb/s SAS interface, it provides the necessary bandwidth to support high-performance hard drives and SSDs, ensuring that your storage subsystem is not a bottleneck. The controller leverages the PCIe 3.0 x8 interface, offering a significant increase in throughput compared to older PCIe generations. This makes it ideal for environments that require rapid data access, such as database servers, virtualization platforms, and high-performance computing clusters. The inclusion of a 1GB cache memory further enhances performance by buffering frequently accessed data and accelerating read and write operations. Beyond raw speed, the 698531-B21 provides comprehensive RAID capabilities, supporting a wide range of RAID levels including 0, 1, 5, 6, 10, 50, and 60. This flexibility allows administrators to configure storage arrays based on specific needs for performance, redundancy, or a balance of both. The battery-backed write cache (BBWC) ensures that data written to the cache is preserved even in the event of a sudden power failure, safeguarding data integrity.
